What is Hives (Urticaria)?

Do you have itchy welts that appear and disappear? Hives are often caused by allergic reactions.
Hives, or urticaria, are red, itchy welts on the skin that appear suddenly. They may result from an allergic reaction, infection, or unknown triggers, and can last from a few hours to several days.

Common Symptoms

  • Raised, red or skin-colored welts
  • Itching or burning sensation
  • Welts that move or change shape
  • Sudden onset, often with a trigger
  • Swelling of lips or eyes in some cases

When to see a dermatologist

  • Hives last more than a few days
  • Swelling interferes with breathing
  • OTC antihistamines don’t help
  • Hives recur frequently
  • Suspected allergic reaction

Early detection is important for managing the condition and preventing further complications.
